We're dividing 555506 by 73 
The aim is to understand the frequency of 73 in 555506.

Step 1:
5 divided by 73 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 73

On to step 2:
55 divided by 73 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 73

Advancing to step 3:
When dividing 555 by 73, we get 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 511 from 555, we get 44.
Include the next digit (5) from the dividend after 44, then repeat: 445 / 73

Advancing to step 4:
When dividing 445 by 73, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 438 from 445 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 73

Moving on to step 5:
73 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 760.0
Subtract 0 from 70 to get 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 73

Step 6:
73 can be fit into 706 9 times, resulting in a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 7609.0
If we take 657 away from 706, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
When dividing 490 by 73, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 7609.6
If we take 438 away from 490, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
73 goes into 520 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7609.67
If we take 511 away from 520, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
The number 73 fits into 90 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 7609.671
If we subtract 73 from 90, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
If we divide 170 by 73, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 7609.6712
Subtracting 146 from 170 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
The number 73 fits into 240 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 7609.67123
If we subtract 219 from 240, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
If we divide 210 by 73, we get 2 and a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 7609.671232
The remainder is 64 after subtracting 146 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
If we divide 640 by 73, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 7609.6712328
If we subtract 584 from 640, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
When dividing 560 by 73, we get 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7609.67123287
Subtract 511 from 560 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 7609.67123287 with a remaining 4.9e-08.
